What defines a ridge in meteorological terms?

A ridge in meteorological terms is defined as an area of elongated high pressure. This feature is characterized by a region where the atmospheric pressure is higher than the surrounding areas, leading to more stable weather conditions. Ridges typically extend in a north-south orientation and can influence weather patterns over large areas. They are often associated with clear skies, light winds, and generally fair weather because the spiraling out of air in a high-pressure system inhibits the formation of clouds and precipitation.

Understanding the concept of a ridge is important for pilots as it impacts flight planning, weather conditions, and potential turbulence. The presence of a ridge can lead to smooth flying conditions, as opposed to areas of low pressure or unstable atmospheric conditions which may be associated with turbulence and adverse weather. Recognizing and interpreting ridges on weather maps helps pilots anticipate changes in weather as they navigate through different air masses.
